In this ecological study, we produce biodiverse animal feed from Flos Sophorae dregs using solid state fermentation process with Rhizopus oryzae and Aspergillus niger. By the orthogonal design method, we analyze the content of crude fiber, crude protein, crude ash from the product, and by multiple regression analysis, we get the result that when the solid state fermentation process with Rhizopus oryzae, the ratio of Flos Sophorae dregs and bran is 2:1 with temperature at 28 degrees C for 72 hours and the inoculation quantity of Rhizopus oryzae is 15 %, the content of crude fiber is 11.31%, the content of crude protein is 42.7%, the content of crude ash is 5.62%, has reached the third-class standard feed; when the solid state fermentation process with Aspergillus niger, the ratio of Flos Sophorae dregs and bran is 2:1 with temperature at 30 degrees C for 96 hours and the inoculation quantity of Rhizopus oryzae is 15 %, the content of crude fiber is 9.77%, the content of crude protein is 34.6%, the content of crude ash is 5.21%, has reached the secondary standard feed.
